The Application No. 11/105,821 that on April 14th, 2005 submitted to, title is " Systemsand Methods For Managing Network Services Between Private Networks " (Serghi etc.).
Technical field
The present invention relates generally to the network service, relate to the mobile gateway that is used for the managing web service particularly.
Background technology
Need the so-called network service of the service of distributing information in communication network.The example that can be called the application of network service comprises reservation system, shopping online or auction site, recreation, multimedia application, calendar, map, chat application, weather demonstration, clock, interactive design application, stock software, currency translation and data input/display system.Along with the generally use to Web browser and Web document format leap platform and equipment scope, many developers adopt Web as applied environment.Web service (WS) is the example of network service, and promptly they are that self-contained, self-described and modular novel Web use, and it represent the technology of the next generation based on web.This is a kind of new technology, below in order to make the reader clearer and look back web service (WS) tout court in order to explain the present invention better.
Web service can be counted as remote procedure call (RPC) technology of complicated measured machine to machine, and its a plurality of foreign peoples' that are used to interconnect the application based on web is suitable for automatic exchange message on public internet.This automation is that world-leading non-technology company (for example retail company) has brought process and the trade benefit based on technology from technology company.
Web service begins to become the basis of the ecommerce of form of ownership; The service of other companies is called to finish business transaction by company.The example of Web service is automatic supply chain management, wherein checks StoreFront by currency agency and buys, and the direct purchased department of the order of stocking up again sends to factory, and charge information collected by general headquarters, and each general headquarters all has their software systems.
Only having fewer companies to participate in business to business (B2B) or the environment of consumer to the transaction of enterprise (C2B), is fairly simple to the management of affiliate's artificial discovery; Yet this becomes complicated along with the growth of the quantity of the growth of the mutual company's number of needs and the interface that they are exported and type.Unified description, discovery and integrated (UDDI) plan provide the standardized method that is used to issue and find the information of serving about web.UDDI is a kind of by different enterprises trustship on the Internet and the single notion register that distributes among the many nodes that duplicate the data that participate in enterprise mutually.
Conceptive, enterprise can register three kinds of information in the UDDI register.Be basic contact details and the identifier that white page provides company, comprise enterprise name, address, contact details and unique identifier.The difference classification of the information description web service (making or sale of automobile enterprise) in the Yellow Page is to enable confirming that based on its classification specific web serves.Green page or leaf provides a description by the behavior of the web service of your enterprise's trustship and the function of being supported.This information comprises the pointer of web service classified information and web service present position.
The Web service application is with code segment and may makes up from the data in public internet somewhere.The framework of realizing the web service can be divided into three zones, comprises communication protocol, service describing and service discovery.But Web service has the interface of describing with the machine processing format, WS descriptive language WSDL specifically, the standard method that it is based on the language of XML (extend markup language) and represents the network service describing.Although for example the internet standard of HTTP (HTTP) is current the most general, yet can use any transmission mode to communicate.
Extend markup language (XML) is a kind of metalanguage, and it realizes the definition or the exchanges data of new term in the document, and (W3C) is specified by World Wide Web Consortium.W3C is the international industry alliance of being created, and in order to make potential performance of Web by the exploitation puppy parc, this has satisfied the needs of the web of extendible and co-operate.W3C is used to develop other main centers of inter-trade standard based on XML.
Some of them are finished in the movable group of XML, and the movable group of this XML attempts to keep balance keeping between stability and the backwards compatibility, thereby impels the encouragement interoperability, and for bringing new group in the XML world.Simple Object Access Protocol (SOAP) thus be a kind ofly to be used for making calling program can communicate with one another in the new mode of the distributed environment switching fabric information of disperseing, creating described environment is to be more prone in order to make programmer write application program.It has defined SOAP header and SOAP Payload, wherein the type (request message, answer message, mistake etc.) of header indication Payload.SOAP uses XML to encapsulate the data of the subprogram that need be sent to remote application, and this provides a kind of message constructing that can be exchanged by various basic agreements.XML is used to from far-end subprogram return data and returns the notice of contingent any error condition.
Current, only there is part web can insert from cell phone, TV, digital camera and car-mounted computer.Mobile web inserts the problem that has interoperability and availability, and described problem makes web be difficult to use in most mobile phone users.The mobile Internet initiative (W3C MWI) of the W3C of in May, 2005 issue proposes to solve these problems by negotiation between the key members in mobile industrial chain, comprises permission instrument distributors, content supplier, handset makers, browser distributors and mobile operator.Current, W3C MWI is devoted at " mobileOK " website, required facility information and marketing and the best practice of expansion activity exploitation of content adaptation,
In addition, there are some problems in current available existing service solution based on the Internet, particularly in wireless/mobile service field.For example, operator is owing to the difficulty of control transaction is avoided opening its mobile device to public infrastructure, and this has lost income.The Web service solution of mobile/wireless client will provide the measured mechanism that realizes controlled access, make that simultaneously operator can be as the middle-agent and to service charging.
In addition, be difficult to make mobile phone than the intercommunication on the internet of big customer's end for example to carry out data base querying; This need combining closely software client and company's background system.Web browser interface efficient in this case is lower, particularly it need penetrate towards the public fire compartment wall etc. with the situation that arrives background server under.
Need provide a kind of and make move and solution that the Fixed Cellular Network client can access network service extranet, promptly a kind ofly provide safety to extranet service to insert, carry out data transaction, support at various web services and XML standard to act on behalf of and the solution of non-standard assembly.

Description of drawings
With reference to the accompanying drawings, by below reading to the specific descriptions of preferred embodiment, aforementioned and other purposes of the present invention, feature and advantage will become obviously, wherein:
Fig. 1 is the block diagram that is equipped with according to the communication system of mobile gateway of the present invention; With
Fig. 2 is the block diagram of the embodiment of mobile gateway of the present invention.
Embodiment
Fig. 1 shows the block diagram of communication system, and it shows a plurality of options that the web service-user is had, and also shows according to mobile gateway of the present invention.The example of Fig. 1 is used to describe the environment that wherein can use web service mobile gateway of the present invention.Two communication networks have been shown in this example, first network 100 and second network 200, it can be by different network provider management.Web service provider 150 management also provides web to serve client to these two networks; Obviously, WS provider of every network is another kind of possible sight.
Web service is provided by logical network 20 and 20 ', and described logical network is called " extranet " or " service network " here; Logical network 20 and 20 ' covers above separately the communication network 100,200, and extranet utilizes borde gateway BG1 to communicate by letter with BG2.Service network 20 makes and can be inserted for the WS terminal use in the other system by each or some the network services that provided in system of company, end-user system EUS or the mobile phone users 1.Service network 20 uses at each and existing standard and the standard developed in these fields.
For example the extranet of extranet 20 is equipped with WS internal services controller (WS-ISC) 5.The role of WS-ISC in extranet 20 keeps and the local extranet service of issuing of management, comprises strategy, safety, register and the system management of using at the end to end network service at least.
Here, " tactical management " is meant that renewal and management are applicable to the constraint (obligation and permission) of the various application of being used by WS to term; Some of them relate to the ad hoc fashion access-in resource, and other the executable permission that is usually directed to is moved, and by which client.Safety management is meant message encryption (at the confidentiality in the network), digital signature (at the transmit leg authentication), other safety certificates etc.For this reason, the diplomatic centralized storage of controller 5 creches, service-level agreement (SLA) etc., and network monitoring data.Term " register management " is meant management and issue WS register 7, and this register contains the tabulation of all available in extranet web services; WS-ISC5 makes client can issue or check, select and locate interested WS.WS-ISC is equipped with GUI server and service entrance; GUI client (or web client) is displayed on the client control device.In above-mentioned Application No. 11/105,732, describe WS-ISC in detail.
In configuration shown in Figure 1, web serves the client that provider 150 offers WS extranet 20 and 20 ' simultaneously.For this reason, each extranet comprises WS external service controller (WS-ESC) 6,6 ', and they communicate with one another by borde gateway BG1 and BG2.As shown in Figure 1, WS-ESC also communicates by letter with each WS-ISC.The role of WS-ESC in extranet 20 is trustship and the outside discovery extranet service of management, and this service is present in other companies, for example company 20 '.Local WS-ESC is dynamically learnt and be transferred into to these external service by borde gateway unit B G1.
BG1 communicates by letter with other boundary elements from other management domains (as the BG2 of extranet 20 ') usually.For example, BG1 and BG2 also carry out exchanging between the territory of new extranet service and their associated metadata (wsdl document, schema file, strategy, service contract etc.).Between this commutation period, BG1 can learn the service of issue in company 20 ', and BG2 can learn the service of company 20.
As shown in Figure 1, the ES of system of company participates in extranet 20 by client gateways CG1, and it is described in detail in above-mentioned patent application 11/105,732.Put it briefly, client gateways comes down to a kind of secure network service broker equipment that is used to realize the web gateway function, supports to be used for the agency of network service and XML " standard " and New Parent.Client gateways is to use hard-wired high-performance equipment to small part, and is arranged to the web service arrangement that realization is undertaken by service network provider.
Obviously, a more than system of company can be connected to extranet 20 by client gateways CG1 separately.The WS that the ES of system of company can use other users by extranet 20 and 20 ' to provide uses.ES also can provide other user's web services of extranet.The network ES of company can be an any kind; Related to the present invention is it provide and/or use within the company's environment and outside specified services.In typical the installation, company's network have the border router R1 that communicates by letter with client gateways CG1, control enter the business of company fire compartment wall, filter the web service business and also have the fire compartment wall of other in-house network operation exchange and routing device, be used to support one or more servers of intranet network service and personal computer etc.
Fig. 1 also shows not the end-user system EUS as the part of specific company system, its explanation private client system.This end-user system can be in the access of edge router ER1 acquisition to network 100, and utilize client gateways CG2 that access to the WS that provides by service network 20 is provided as shown, perhaps can utilize client gateways CG1 to obtain access to extranet 20.
Mobile phone users is also referred to as " mobile WS user ", also can utilize web service (WS) mobile gateway 10 and the web service that provides by service network 20 is provided, and this is a purpose of the present invention.The example of mobile phone users 1 is portable computer system, PDA, mobile " smart phone " etc., and it is the client of wireless network 2; The client of network 2 inserts the WS that is provided by extranet 20 and 20 ' by the router R3 that is connected to mobile gateway 10.Router R3 can carry out the wireless conversion to landline of signal between two networks; Perhaps alternatively, described conversion can be performed at mobile gateway 10 places.
Along with web service becomes at business to business (B2B) working application (for example purchase/manufacturing order) and consumer enterprise (C2B) working application (C2B e-commerce operations for example, wherein company sells product or service to the individual) advantage mechanism, mobile gateway 10 becomes to be used to have and moves or the vitals of the web service extranet of long-range employee's large enterprise.It has also been realized at information station, sensing network and other new service opportunities to the non-traditional use of radio infrastructure.Its value source is from the value of extranet service itself.WS mobile gateway of the present invention attempts to provide a kind of making to move the solution that can insert web service extranet with the Fixed Cellular Network client.
Fig. 1 also shows the universal network node (router, switch) 16 by network 100 routes/reciprocal exchange of business, and exchanges the router one 5 that SOAP call out by extranet 20.For the web service that provides for it is advertised, mobile phone users 1 sends in order to indicate it to wish service separately is added into the SOAP request of WS available on the extranet 20 to controller 5; The information that it sends to WS-ISC 5 comprises the position of service, the description of service, related strategy and/or SLA, charge information etc., so that when service is published, the user will have all required information of this service of use.
When mobile subscriber 1 wished to use service available on the extranet, it asked at first to check that register is to search and to select interested service; In case service, address of service and related registration, mandate, safety and other are tactful to be checked and reach agreement, mobile subscriber 1 just can bring into use this service.In this arrangement, mobile subscriber 1 can the interested complicated applications of long-range execution and need not by communication network 100 to/upload and data download from application site.This operator scheme is particularly advantageous for the mobile device that does not have the larger process ability.
The virtual extranet service inlet that may be implemented as software application in the mobile gateway 10 makes that mobile subscriber in the network 2 and network are served the provider can be mutual with service network 20.This inlet makes the user can login extranet 20 and authenticates himself by means of associating identity or another authentication mechanism, provides or use selected service then.The operation that for example shows various service lists, description etc. also is feasible, and this can not have influence on the terminal use basically and how provide and/or use the network service.
WS mobile network 10 a kind ofly disposes, has the high performance hardware based edge device of embedded software by network provider, as hereinafter the block diagram in conjunction with Fig. 2 is described.Fig. 2 shows the block diagram of the embodiment of mobile gateway of the present invention.Term " enter " and " advancing " be used for indication from mobile phone users network 2 to service network 20,20 ' direction, and term " is gone out " and " oppositely " is used for indicating from service network 20, the 20 ' direction to mobile phone users network 2.Should be appreciated that these all are for convenience and the term of the relativity of using here.Term " requesting party " and " provider " are respectively applied for the entity that the expression request inserts special services and special services is provided, and term " interested service " is meant that interested WS uses for the requesting party.
In addition, the term in this specification " user " is meant the client of extranet 20, and described extranet for example can be a mobile phone users network 2, or mobile WS terminal use, the user terminal that is connected to mobile phone users network 21 as shown in Figure 1.
The web that WS mobile gateway 10 makes mobile WS terminal use 1 to use to be provided by extranet 20 serves.Gateway 10 is included in mobile phone users network interface (MUN) 30, WS/XML logical block 40 and the extranet interface processor 50 of mobile WS terminal use 1 one sides.
In direction of advance, as shown, the business that mobile phone users network (MUN) interface 30 comes termination to enter by incoming tunnel termination unit 31.The packet filtering that incoming tunnel termination unit 31 will enter in the business becomes to comprise second type grouping that first type of the grouping of carrying WS business divides into groups and comprises the grouping of carrying non-WS business.Term " WS grouping " and " non-WS grouping " are used to represent described type of service.Incoming tunnel termination unit 31 sends non-WS business to the destination by the router one 6 of data network 200, and for authenticating the WS business is sent to piece 33.Should also be noted that term " grouping " has general implication in this manual, it is meant the datagram of any kind of carrying WS and non-WS business.
The classification of these two kinds of packet types is carried out in application layer.Incoming tunnel termination unit 31 knows that by all being entered the detection of professional execution deep packet the SOAP based on WS enters business (until the soap protocol rank).The address that unit 31 will enter grouping converts L7 address the private room that virtual extranet covers to from public address (IP or other agreements), and with extranet 20 employed L2-L4 protocol-independents.Mobile/land protocol conversion operation that unit 13 can also be carried out; Yet these operations can be performed in different conversion unit of protocol.
Incoming tunnel termination unit 31 can for example be the GTP tip node that XML realizes, it filters the WS/XML request and they are sent to WS/XML logic rather than data network; GTP is the standard of specifying the interface that is used for GPRS (GPRS) tunneled protocol.Also can use wave point of equal value.
Authenticated user administration module 33 is carried out and is used for the authentication section that the user inserts the strategy of extranet; Have only authenticated user just can share by having the web service that other entities that web service can be provided provide.Module 33 is implemented acts of authentication and is transmitted or abandon communication service in response to this acts of authentication based on the rule of provider's appointment.It need be from requesting party's user ID and password.In other words, authentification of user administration module 33 utilizes the extranet service provider to authenticate, rather than should be used for authenticating as the web service that utilizes at present appointment in the company.The WS mobile gateway realize service consumer to the single-sign-on (SSO) of extranet thus spanning network inserts a plurality of web services.
In inverse direction, interface 30 comprises endpoint resolution adaptation unit 35, and it follows the tracks of the mobile device 1 by 2 services of mobile phone users network, and feasible business adapts to variation in the network 2 (for example bandwidth change etc.).Incoming tunnel creating unit 34 carry out the grouping of the professional and carrying XML of non-WS that land/mobility protocol conversion operations, the polymerization router one 6 by network 200 receives and by the resulting business of mobile phone users network 2 transmissions to the destination.In some network designs, unit 34 can be that the GTP that XML realizes creates point.
Mobile network's logical block 40 comprises device management unit 41, strategy execution/defining point 42 and safety execution point 43, and it has related database: equipment/resource management database 44, policy database 45 and service-level agreement contract database 46.40 pairs of WS groupings of logical block are carried out from being used to carry the conversion of the employed any agreement of grouping of WS business to the L7 layer protocol.As mentioned above, SOAP (Simple Object Access Protocol) is current is used for transmission web service message between web client and web service is used.Logical block 40 also will convert mobile network's 2 employed agreements to from L7 agreement (for example SOAP) by the WS grouping that extranet receives.
Therefore, in direction of advance, device management unit 41 can be created the XML encapsulation that is used for non-XML business; With message had any format conversion becomes based on XML web service message.For for the business of SOAP, message is examined to set up message classification (request, answer) and to be provided for Policy Enforcement Point 42.Equipment control 41 also carry out deep packet detect, with the data qualification that enters and to be divided into the control that will be transmitted to web service controller 5 professional and will be transmitted to the XML data service of WS destination.In inverse direction, if the request conversion operations, then the XML encapsulation is made into the form that the user was familiar with of request WS separately again by termination and SOAP Payload.
For direction of advance, strategy execution/defining point 42 relates to carries out strategy and the SLA contract that is suitable for to the business that enters.Be based on WS's and at point 42 executable strategies, and be stored in the policy database 45 based on the strategy of non-WS (for for example QoS, SLA, keep a diary, the demand of monitoring etc.).For example, policy point 42 confirms at first whether the SOAP request that enters is to serve at the web that the requesting party can use.Then, it can confirm whether the content of soap message is effective.This and network layer are similar, check the validity of IP packet header in network layer.
Equally, policy point 42 uses SLA (service-level agreement) set that is stored in the SLA contract database 46 they are put on the business that enters.Abandon not in accordance with the strategy in the database 45 or the business of the SLA contract in the database 46 at this point.Like this, network can not taken by inconsistent business, just can be dropped up to arriving the destination in inconsistent business described in the current realization.
WS descriptive language (WSDL) file is used for service describing.This is the accessible standard of machine, it has defined needed all information of method of WS client call WS, for example agreement and the message format that each remote call-in is permitted in individual process title and signature, data type, the extranet, be used to URL that inserts this WS etc.Wsdl document has also been specified the one or more network sites that can call the provider, and some information about desired message exchange pattern can be provided.In fact, service describing representative management is used for carrying out with this service the agreement of mutual mechanism.Equally, policy point 42 also can be according to the requirement among the WSDL or the existing extranet policy that is used to insert special services revise message.
End-to-end communication between any other client of the compliance of safety execution point 43 execution business and safe access standard, the authenticated user in the protection service network and the end-to-end communication between the service network 20 and service network and service network.Therefore, safety carry out point 43 can be to entering the measured WS safe practice of service implementation: WS-safety, XML-encrypt and XML-signature and other can be used for improving the technology of secure communication.These technology based on the web service standard guarantee that the user of authentication service in system of company and the mobile phone users network can add virtual extranet service network 20.In certain embodiments, also can implement additional safety regulation to communication service.For inverse direction, safety is carried out point 43 and is responsible for involved in signature de and decrypt messages.
In inverse direction, policy definition/execution point 42 is responsible for coming transformation service according to the strategy that is applicable to reverse traffic and the SLA contract of mobile phone users network 2.In this case, point 42 executable strategies be the WS strategy that is applicable to mobile network 2 (demand with WS level, for example safety, QoS, SLA, charge to daily record, monitoring etc.).Equally, policy point 42 is used SLA set that is stored in the database 46 and the suitable SLA that reverse traffic is implemented mobile phone users 1.Be not dropped at this point in accordance with strategy in the database 45 or the business of the SLA in the database 46.
